Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed...

Nd2Zr2O7 is a new candidate for quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field ground state...

Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted....

ZnCr2Se4 is a magnetically frustrated spinel compound with an incommensurate helical ground state. It has a pyrochloremagnetic sublattice which is formed by Cr3+ (S = 3/2)...

Yb2Pt2Pb is a first-in-class system where spin ladders are coupled to quasiparticles, made massive by strong quantum mechanical fluctuations. The classical Yb moments are...

Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

Geometrically frustrated spin systems have been studied extensively for decades because of many intriguing phenomena, exemplified by the non-magnetic quantum disordered states....
